TECHNICAL FIELD

This disclosure relates to a belted absorbent article comprising a chassis and a pair of belt portions forming a belt around a waist of a wearer. The belted absorbent article may be provided in various sizes.

BACKGROUND

Absorbent articles in the form of disposable diapers are generally known in which the diaper is provided with a fastening system including a pair of fastening tabs secured to both sides of one end region of the diaper. The fastening tabs are intended to engage receiving means located on the other end region of the diaper. Such a diaper is generally placed on the wearer when the wearer is lying down. While the above-described fastening arrangement is satisfactory when applying diapers to a young child or baby, problems can arise when trying to fit an incontinence diaper to an adult wearer. This is particularly true for wearers who wish to apply the diaper to themselves, or for caregivers who receive a significant benefit from applying the diaper when the wearer is in a standing position. To address this issue, a belted absorbent article has been developed, which allows a wearer or caregiver to apply the diaper in a standing position.

A belted absorbent article typically has a belt attached integrally with the chassis or the absorbent article. The belt may have two belt portions extending on either side of the rear end of the chassis or the absorbent section. The two belt portions are intended to be fastened around the waist of the wearer, whilst the front end of the absorbent section hangs down between the legs of the wearer. Once the belt portions have been joined together, the wearer can reach between his or her legs to draw up the absorbent section between the legs and to attach the free end of the absorbent section to the belt portion. Similarly, the article can be made so that the belt is fastened to the front portion of the article and is secured around the back of the wearer. In this case, the absorption section will be hanging down in the front and will be secured to the belt in the back. This type of article is particularly useful for caregivers who care for patients that may have dementia or the like.

For persons having weaker eyesight, it may be appropriate to provide each belt portion with means for identification and distinction of the different ends of the belt portions from each other. As an example, US 2002/032425 A1 discloses an absorbent article comprising a pair of belt portions attached to the rear portion, alternatively the front portion of the article, in which the belt portions are provided with at least one means for identification and distinction of the different ends of the belt portions from each other. By distinguishing the different ends of the belt portions from each other, it is believed that the wearer is guided on how to apply the article as soon as the article is unfolded from its folded state and the belt portions are unfolded, i.e. hanging loose from the rear portion.

However, despite the activity in the field, exemplified by the above-cited disclosure, there remains a need for an improved belted absorbent article.

SUMMARY

An object of the present disclosure is to provide an improved belted disposable article, in which the belted portions are easy and quick to open up already when the belts are in a folded configuration.

The disclosure concerns a belted disposable article. The belted disposable article comprises a chassis having first and second end portions and a central portion extending therebetween. The chassis includes a first covering layer having a first surface intended to face towards the user and a second surface intended to face away from the user in use. The article further comprises a pair of belt portions attached to the chassis so that a first belt portion and a second belt portion extend on each side of the first end portion of the chassis for securing to each other around a waist of a wearer of the article to form a belt having an exterior surface.

The first belt portion has a free end which carries a fastener adapted to be attached to an exterior surface of the other of the belt portions. The second end portion of the chassis comprises a fastening device for securing the second end portion of the chassis to the belt portion so that said article assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. Moreover, the first and second belt portions are folded over the first surface to form a folded belt configuration prior to use of the article. Thereby, the first belt portion is arranged on top of the second belt portion. In addition, a belt-opening trigger zone is disposed on the first belt portion and arranged adjacent the free end of the first belt portion.

In this manner, a wearer or caregiver is not only guided to identify the free end of the first belt portion when the belt portions are in the folded belt configuration, but also triggered to open up the belt portions, i.e. at least unfold the first folded belt portion, prior to place the belt (belt portions) and the article around the waist of the wearer. In other words, the belt-opening trigger zone is adapted to identify the free end of the first belt portion when the belt portions are in the folded belt configuration and to trigger a wearer or caregiver to initially unfold the belt portions into an unfolded belt configuration. In this context, the unfolded belt configuration refers to a configuration in which each one of the belt portions are unfolded from the first surface of the chassis. A belt-opening trigger zone arranged adjacent the free end of the first belt portion is also useful to distinguish the free end of the first belt portion from the other end of the first belt portion, which is permanently attached to the chassis. In many types of belted articles, the free end and the other permanently attached end of the belt portion are essentially considered identical when being arranged in the folded belt configuration. Thus, by the provision of having the belt-opening trigger zone arranged adjacent the free end of the first belt portion, it becomes possible to reduce the risk of having a wearer or caregiver trying to open up the belt portion at the wrong end, i.e. the permanently attached end. To this end, the example embodiments of the disclosure provides the advantage that less considerations is needed to find the free end of the belt portion already when the article is in the folded belt configuration.

Further advantages are achieved by implementing one or several of the features of the dependent claims.

In one example embodiment, the belt-opening trigger zone defines a pointer directing a user to the free end of the first belt portion when the belt portions are in said folded belt configuration. In this manner, the risk of having a wearer or caregiver trying to open up the belt portion at the wrong end is even further reduced.

By way of example, the belt-opening trigger zone resembles the shape of an arrow directing a user to the free end of the first belt portion when the belt portions are in the folded belt configuration.

The belt-opening trigger zone can be disposed on the first belt portion in several different ways. As an example, the belt-opening trigger zone is a printed belt-opening trigger zone. Alternatively, the belt-opening trigger zone is an embossed belt-opening trigger zone. In yet another example, the belt-opening trigger zone is a combined printed and embossed belt-opening trigger zone.

In addition, or alternatively, the said belt-opening trigger zone is a label attached to a surface of the first belt portion. A combination of a label and printed and/or embossed belt-opening trigger zone is also conceivable.

According to one example embodiment, a remaining belt section of the first belt portion has an essentially uniform non-patterned exterior surface.

By way of example, the remaining belt section of the first belt portion is free from distinguishable indicators.

In some example embodiments, any one of the first and second belt portions comprises an intermediate elastic region.

According to some design variants, the belt-opening trigger zone comprises a tactile region having a tactile characteristic different than the other parts of the first belt portion. A tactile region having a tactile characteristic different than the other parts of the first belt portion can be provided e.g. by using a different material of belt opening trigger zone than the other parts of the first belt portion. In addition, or alternatively, a tactile region having a tactile characteristic different than the other parts of the first belt portion can be provided by treating the material or surface of the belt-opening trigger zone, e.g. by coating, embossing or the like.

In addition, or alternatively, the belt-opening trigger zone may comprise a visual region having a colour characteristic different than the other parts of the first belt portion.

In some design variants, the belt-opening trigger zone comprises a plurality of belt-opening trigger zone elements. As an example, each one of belt-opening trigger zone elements are provided in the form of an arrow defining a pointer directed towards the free end of the first belt portion. Further, each one of belt-opening trigger zone elements may typically be arranged to form a pattern over a surface of the first belt portion. With “a pattern” is meant herein an organised arrangement of at least one belt-opening trigger zone element. Such a pattern may be formed by various types of belt-opening trigger zone elements.

The belt-opening trigger zone may have a length in the transversal direction of the belt of about 5-40 mm, preferably a length in said direction of about 10-35 mm, still preferably a length in said direction of about 20-30 mm.

The belt-opening trigger zone may have a length in the longitudinal direction of the belt of about 10-40 mm, preferably a length in said direction of about 15-30 mm, still preferably a length in said direction of about 20-30 mm.

Typically, the belt-opening trigger zone is arranged on the exterior surface of said first belt portion.

According to one example embodiment, a second belt-opening trigger zone is disposed on the second belt portion and arranged adjacent a free end of the second belt portion. The second belt-opening trigger zone may incorporated any one of the examples, features, functions and/or arrangements as described in relation to the belt-opening trigger zone above besides that the second belt-opening trigger zone is arranged on the second belt portion instead of the first belt portion.

Typically, although not strictly necessary, the second belt portion is arranged to overlap an absorption portion of the article and the first belt portion is arranged to overlap the second belt portion. Thus, when the first and second belt portions being folded over the first surface to form the folded belt configuration prior to use of the article, the second belt portion is arranged to overlap an absorption portion of the article and the first belt portion is arranged to overlap the second belt portion so that a fastener on the free end of the first belt portion is releasably attached to the exterior surface of the second belt portion.

In one example embodiment, the second belt portion is releasably attached to the first surface of the first covering layer by a breakable adhesive. Thus, when the first and second belt portions being folded over the first surface to form the folded belt configuration prior to use of the article, the second belt portion is releasably attached to the first surface of the first covering layer by a breakable adhesive.

Analogously, the first belt portion is releasably attached to the exterior surface of the second belt portion by a breakable adhesive. Thus, when the first and second belt portions being folded over the first surface to form the folded belt configuration prior to use of the article, the first belt portion is releasably attached to the exterior surface of the second belt portion by a breakable adhesive.

In some design variants, a part of the free end adjacent a free end edge is distinguished from the remaining parts of the article by colour, pattern or the like.

Typically, although not strictly necessary, a part of any one of the first and second belt portions, which extends from the first end portion of the article, is permanently attached to the first end portion.

In some example embodiments, the belted article is a disposable absorbent article such as a diaper and an incontinence guard.

In some example embodiments, the belted article has an absorption body arranged between a first liquid-permeable covering layer and a second substantially liquid-impermeable covering layer.

Further features of, and advantages with, the example embodiments of the present disclosure will become apparent when studying the appended claims and the following description. The skilled person realize that different features of the example embodiments may be combined to create embodiments other than those described in the following, without departing from the scope of the present disclosure.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Various aspects of the disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The example embodiments of the disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein; rather, these embodiments are provided for thoroughness and completeness. Like reference character refer to like elements throughout the description.

For purposes of description herein the terms “rear,” “front,” “vertical,” “horizontal,”, “longitudinal,”, “inner,” “outer,”, “exterior,”, “interior”, and derivatives thereof relate to the example embodiment of the disclosure as oriented in e.g. FIG. 2. However, it is to be understood that the example embodiments may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the examples illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments. Hence, dimensions and other physical characteristics relating to the example embodiments disclosed herein are not to be considered as limiting, unless the appended claims expressly state otherwise.

The disclosure mainly refers to disposable absorbent articles, which means articles that are not intended to be laundered or otherwise restored or reused as absorbent articles after use. The disclosure further relates to a disposable article of the belt type, a so-called belt article or belted article. Thus, hereinafter, the belted disposable absorbent article may be referred to as the belted absorbent article, the belted disposable article, the belted article, the belt article or simply as the article.

The article comprises generally a belt and a chassis part. Belted articles comprise a transverse belt connected to either the front or rear end part of the article's chassis part. When applying such a belt article, the belt is fixed in a first stage around the user's waist. The chassis part of the belt article is hanging loosely from the belt in this type of article. The chassis part is then led between the user's legs and attached to the belt, wherein the belt comprises fixing surfaces intended to stick fast to a fixing member or fastening device arranged on the chassis part by its free transverse edge.

FIGS. 1 and 2 schematically show some components of a belted article 10 according to an example embodiment of the disclosure, in which the belted article 10 is shown from the side which is intended to face towards the wearer when in use.

The belted article 10 comprises a chassis and a waist belt 15. The belt in this exemplary embodiment includes a first belt portion 16 and a second belt portion 17. Further, the belted article 10 has a longitudinal direction X and a transverse direction Y. The chassis part 12 comprises a first covering layer 20. In other words, the belted article has a length extension in the longitudinal direction X and a width extension in the transverse direction Y. Moreover, the chassis 12 has a first end portion 18, a second end portion 14 and a central portion 12 a extending therebetween.

The chassis includes the first covering layer 20, which has a first surface 21 intended to face towards the user and a second surface 22 intended to face away from the user in use.

In other words, there is provided a belted disposable article 10, which comprises the chassis 12 having first and second end portions 18, 14 and a central portion 12 a extending therebetween. The chassis also comprises the first covering layer 20 having the first surface 21 intended to face towards the user and the second surface 22 intended to face away from the user in use.

In this exemplary embodiment, as shown in FIGS. 1 and 2, the first end portion is a rear end part 18 and the second end portion is a front end part 14.

The article further comprises a pair of belt portions 16, 17 attached to the chassis 12 so that the first belt portion 16 and the second belt portion 17 extend on each side of the first end portion 18 of the chassis for securing to each other around a waist of a wearer of the article to form the belt having an exterior surface 16 a, 17 a. Thus, each first and second belt portions 16, 17 are connected to the chassis 12 in the rear end part 18, respectively. The first belt portion 16 is joined to the longitudinal edge 2 and the second belt portion 17 is joined to the opposing longitudinal edge 1.

Typically, although not strictly required, the belt portions may be partly or entirely elastic. Thus, hereinafter, the waist belt may sometimes also be referred to as the waist elastic belt, the elastic belt or simply as the belt. The belt 15 of the belted article 10 is intended to encircle a user's waist. In other words, the belt portions 16, 17 forming the belt are intended to encircle a user's waist. The belt here has an inner surface 19 facing the wearer during use and an outer (exterior) surface 16 a and 17 a facing away from the wearer during use, wherein said belt comprises the first belt portion 16 and the second belt portion 17. In the belted article shown in FIGS. 1 and 2, the belt portions (first belt portion 16 and second belt portion 17) extend in the transverse direction Y of the belt article. The belt portions (first belt portion 16 and second belt portion 17) extend also in the longitudinal direction X.

The first belt portion 16 and the second belt portion 17 are attached to the chassis 12 so that said first belt portion 16 and said second belt portion 17 each extends on each side of the first end portion of the chassis for securing to each other around a wearer of the article. To this end, as will be further described hereinafter, the first belt portion 16 has a fastener or a fastening component adapted to be attached to second belt portion 17 for securing the belt portions to each other around the wearer of the article.

In this example, as shown in e.g. FIGS. 1-3 a, the first belt portion has a free end 11 which carries the fastener 51 adapted to be attached to an exterior surface 17 a of the other of the belt portions, i.e. the second belt portion 17. The exterior surface 17 a of the other of the belt portions may in some examples be provided with a mating fastening component (not shown). Further, each one of fastener 51 and the mating fastening component may comprise a mechanical connector structure being capable of forming a mechanical interconnection with each other. One example of a mechanical connector structure is a hook and loop material. Hereby, the fastener and the mating fastening component are mechanically connectable to form an interconnection between said first belt portion and said second belt portion for securing to each other around a wearer of the absorbent article.

As mentioned above, the second end portion 14 of the chassis comprises a fastening device 48, 49 for securing the second end portion 14 of the chassis to the belt portion so that the article assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. The second end portion 14 of the chassis is typically secured to the exterior surfaces 16 a, 17 a of the first belt portion 16 and/or second belt portion 17.

In other words, the front end part, i.e. second end portion 14 of the chassis includes the fastening device(s) 48, 49 for securing the front end part of the chassis to the belt.

Turning now to FIG. 2, the article is depicted in a state in which the first and second belt portions 16, 17 are folded over the first surface 21 of the first covering layer 20 to form a folded belt configuration prior to use of the article. Hereby, the first belt portion 16 is arranged on top of the second belt portion 17. Further, FIG. 2 illustrates a belt-opening trigger zone 50 being disposed on the first belt portion and arranged adjacent a free end 11 of the first belt portion 16. The belt-opening trigger zone 50 will be described further in particular with respect to FIG. 3a-3c hereinafter. It should be readily appreciated that the features, functions, examples and details of the belt-opening trigger zone 50 as described in relation to the FIGS. 3a-3c may be incorporated into an article as described in conjunction with FIGS. 1 and 2.

Turning now again to FIG. 2, the belted article is here depicted in its folded belt configuration. As illustrated in FIG. 2, the second belt portion 17 is arranged to overlap the chassis of the article and the first belt portion 16 is arranged to overlap the second belt portion. In other words, the second belt portion 17 is arranged to overlap the first end portion 18 of the chassis 12 and the first belt portion 16 is arranged to overlap the second belt portion 17. In this example embodiment, the second belt portion 17 is arranged to overlap an absorption portion of the article and the first belt portion 16 is arranged to overlap the second belt portion 17. Thus, when the first belt portion 16 and the second belt portion 17 are folded over the first surface 21 to form the folded belt configuration prior to use of the article, the second belt portion 17 is arranged to overlap the absorption portion 40 of the article and the first belt portion 16 is arranged to overlap the second belt portion 17. To this end, the fastener 51 on the free end 11 of the first belt portion is releasably attached to the exterior surface 17 a (see e.g. FIG. 3a ) of the second belt portion 17.

Further, the second belt portion 17 is releasably attached to the first surface 21 of the first covering layer 20 by a breakable adhesive. In other words, when the first belt portion 16 and the second belt portion 17 are folded over the first surface 21 to form the folded belt configuration prior to use of the article, the second belt portion 17 is releasably attached to the first surface 21 of the first covering layer 20 by a breakable adhesive.

Analogously, the first belt portion 16 is releasably attached to the exterior surface 17 a of the second belt portion 17 by a breakable adhesive. In other words, when the first belt portion 16 and the second belt portion 17 are folded over the first surface 21 to form the folded belt configuration prior to use of the article, the first belt portion 16 is releasably attached to the exterior surface 17 a of the second belt portion 17 by a breakable adhesive.

It is to be noted that the term belt portion, belt half, or belt end section, does not mean that the two belt portions, belt halves, or belt end sections, must be of the same length. In alternative embodiments, one belt portion can be longer than the other. It is important, however, that the combined length of the two belt portions reaches around a user's waist. In an alternative aspect of the disclosure, the two belt portions 16, 17 of the belted article 10 can consist of only one piece of material, which piece of material extends in the transverse direction Y across the entire rear end part 18 and past the respective longitudinal edges 1, 2. The belt 15 can, in accordance with other alternative aspects of the disclosure, be inelastic or partly elastic. A partly elastic belt means that certain parts of the length of the belt have elastic properties, while certain other parts of the length of the belt do not have elastic properties.

In some design variants, any one of the first and second belt portions 16, 17 comprises an intermediate elastic region (not illustrated).

As mentioned above, the belted article 10 here comprises a first covering layer 20, wherein the first covering layer comprises the first surface 21, intended to face towards the user when the belted article 10 is used. The belted article 10 here also comprises the opposing second surface 22. Typically, although not strictly necessary, the first covering layer 20 of the belted article 10 has an hourglass shape. Other shapes such as a rectangular shape, for example, may also be conceivable in other design variants.

The first covering layer 20 can consist of any material suitable for the purpose. The most common covering materials for disposable articles are nonwoven textile materials, so-called nonwoven materials manufactured according to various methods. Not so common but also occurring is the use of covering layers 20 of woven material or net material. For example, a nonwoven material suitable as a covering layer 20 can be manufactured from synthetic fibres such as polyester or polypropylene, of natural fibres such as cotton fibres. A mix of synthetic and natural fibres also occurs. The manufacture of a nonwoven material consists of the two main stages web formation and web bonding. Web formation means that a web is created of as even a surface weight as possible, wherein the web can be created by carding of natural or manmade staple fibres. The spunlaid technique is another web-forming technique, in which polymer material is extruded to thin continuous fibre threads on a continuous conveyor. The extruded thin fibre threads are randomised following extrusion in that they land on the continuous conveyor in a random manner. Web formation can take place in several different ways. A commonly occurring method is so-called thermal bonding, wherein a bonding pattern is melted into the fibre web in a roller nip where at least one of the hot rollers has a pattern. For web formation by means of thermal bonding to work, at least a certain portion of the fibres in the web must consist of synthetic fusible fibres. Occurring bonding patterns are dots of varying geometry, small rectangular or circular surfaces, floral patterns or the like. What is common to the methods described above, and also to other methods, is that not all the surface of the covering layer 20 is bonded, but between the bonding areas the covering layer has open areas comprising fibre threads that are fixed at one or both of their ends to the adjacent bonded areas.

Laminate consisting of two or more of the aforementioned possible covering materials also occur, such as a covering consisting of different materials in different parts of the surface. It also occurs that the covering layer 20 consists of an entirely or partially elastic material to give the belt article 10 a better fit when in use. The covering layer 20 also has a fastening device (e.g. a first and a second fastening devices 48, 49) arranged at the respective longitudinal edge 1, 2 in the front end part 14 of the covering layer 20, i.e. connected to the two front corners of the covering layer 20. The fixing members 48, 49 are arranged on the side of the covering layer 20 that is intended to face towards the user when the belted article 10 is used. The fastening device 48, 49 may typically comprise hook elements that are intended, on application of the belt article 10 to a user, to be connected detachably to loops arranged on the side of the belt 15 that is intended to face away from the user.

In other words, said second end portion 14 of the chassis typically includes a fastening device 48, 49 for securing the second end portion 14 of the chassis to the waist belt 15. Typically, the second end portion 14 of the chassis typically includes a fastening device 48, 49 for securing the second end portion 14 of the chassis to the first belt portion 16 and/or second belt portion 17.

In some design variants, the fastening device 48, 49 can consist of separate fastening tabs that are connected permanently to the front end part 14 of the belted article 10, wherein the fastening tabs extend outside the edges of the belted article 10. The hook elements are in this case arranged on the fastening tabs.

When a belted article 10 is to be applied to a user, the belt portions 16 and 17 (forming the belt 15) is first fixed around the user's waist. The front end part 14 of the belt article 10 that hangs loosely is then led in between the user's legs, following which the fastening device 48, 49 is fixed to the belt portions 16 and 17 (i.e. the belt 15) on the stomach on the side of the belt 15 oriented away from the user. The hook elements of the fastening device are fixed in this case to loops arranged on the surface of the belt 15 oriented away from the user, e.g. belt portion surfaces 16 a and 17 a. A belted article is also conceivable in which the belt is connected to the front end part of the belt article. Such an article is applied to the user in the reverse manner, i.e. after the belt has been fixed around the user's waist, the loosely hanging rear end part is led in between the user's legs and fixed to the belt at the back on the side of the belt oriented away from the user.

To improve the fit of the belted article 10, the longitudinal edges 1, 2 of the first covering layer 20 can be provided with leg elastic 45 arranged substantially in the longitudinal direction X of the article. The task of the leg elastics 45 includes improving the fit of the article, and making the belt article 10 more like textile multiple-use briefs/pants. The respective leg elastic 45 can consist of one or more elastic threads that in the extended state have been joined to the covering layer 20 by gluing, ultrasonic welding or the like. Alternatively, the respective leg elastic 45 can consist of elastic ribbon material of foamed material, for example. The respective leg elastic 45 may be arranged on the side of the first covering layer 20 that is intended to face away from the user when in use.

The rear or front end parts 18, 14 of the belted article 10 can also be provided with so-called waist elastic 46 in the form of elastic elements arranged along a second transverse edge 5 or a first transverse edge 4 of the belted article 10 to give the belt article 10 a soft, flexible enclosure of the user's waist. In FIG. 1, only the front end part 14 of the belted article 10 is provided with waist elastic 46. The waist elastic 46 consists of a thin strip of elastic foam material that is attached by glue to the side of the first covering layer 20 that is intended to face away from the user. The waist elastic 46 is applied in a stretched state to achieve a holding-together force that stretches the belted article 10 around the user's waist. When the fastening device 48, 49 are fastened to the belt 15, it is suitable that the waist elastic 46 is tensioned in the transverse direction Y of the belt article 10 so that the front end part 14 has a smooth configuration over the user's stomach on use.

According to another aspect of the disclosure, the belted article 10 comprises a second covering layer 30 arranged on the side of the first covering layer 20 that is intended to face away from the user when in use. The second covering layer 30 has the same extension in the X/Y plane as the first covering layer 20. The second covering layer 30 is typically substantially liquid-impermeable, but other types of covering layer can also exist. The second covering layer 30 can consist of a range of different materials, but most frequently it consists of a thin, preferably liquid-impermeable plastic film, but it is also possible to use other types of substantially liquid-impermeable material such as nonwoven material that has been made substantially liquid-impermeable through plastic coating, for example, a liquid-impermeable foam layer, liquid-impermeable glue or the like. The second covering layer 30 can alternatively consist of a liquid-impermeable vapour-permeable material, a so-called breathable material. Furthermore, laminates comprising at least one liquid-impermeable and typically breathable layer arranged against the second surface 22 of the first covering layer 20 also exist as a second covering layer 30. These laminates usually consist of a liquid-impermeable material acting as a barrier against soaking through and a more textile-like material arranged on the side of the belt article 10 that is oriented away from the user on use. The outside of the belted article 10 is thereby more garment-like in use. The textile-like layer of the laminate normally consists of a nonwoven layer, but other textile or textile-like materials also exist. The first covering layer 20 and the second liquid-impermeable covering layer 30 can be joined to one another in several different ways. Examples of joining methods are gluing, thermal fusing, ultrasonic welding or the like. For belted articles 10 comprising a first covering layer 20 and a substantially liquid-impermeable second covering layer 30, it is suitable for the leg elastic 45 and the waist elastic 46 described above to be arranged between the two covering layers 20, 30. The first covering layer 20 may, in a belted article 10, have a low absorption capacity wherein smaller bodily secretions such as occasional drops of urine, for example, initially secreted menstruation fluid or similar.

According to one example embodiment of the disclosure, as shown in FIGS. 1-2, the belted article 10 has an absorption body 40 arranged between the first covering layer 20 and the second substantially liquid-impermeable covering layer 30. The first covering layer 20 of a belted article according to this example must be liquid-permeable. The belted article 10 in accordance with this example relates to a diaper intended to be used by an incontinent adult person or by a child who has not yet become continent. The absorption body 40 has substantially the same profile, but a smaller surface, than the first and second covering layers 20, 30. The two covering layers 20, 30 thus extend outside the edges of the absorption body 40 along the entire circumference of the absorption body 40. The absorption body 40 has, exactly like the covering layers 20, 30, a front and a rear end part and a narrower crotch part located between the end parts. Upon use of a belted article comprising the absorption body 40, the front part of the crotch part and the front end part principally act like a receiving area for urine, while the rear part of the crotch part and the rear end part act mainly as a receiving area for faeces. The liquid-permeable first covering layer 20 and the substantially liquid-impermeable second covering layer 30 are connected to one another outside the absorption body 40 along its entire circumference. The absorption body 40 can be constructed from one or more layers of cellulose fluff pulp. The cellulose fluff pulp can be mixed with fibres or particles of a highly absorbent polymer material, so-called super absorbents, of the type that chemically binds large quantities of fluid on absorption with the formation of a fluid-holding gel. The absorption body 40 can also comprise highly absorbent polymer material arranged in a layer inside the absorption body or connected to the surface or surfaces of the absorption body. The absorption body 40 can further include further components for improving the properties of the absorption body 40. Examples of such components are binding fibres, various types of fluid-dispersing layers or fibres, dimensionally stabilising components, reinforcing fibres or the like.

Turning now to the FIGS. 3a-3c , there is depicted an enlarged view of a section of the belt 15, i.e. the first belt portion 16 and the second belt portion 17, of an article described in conjunction with in FIGS. 1 and 2. As mentioned above, the first belt portion 16 of the waist belt is intended to be interconnected to the second belt portion 17 by the fastener 51 for securing to each other around a wearer of the belted absorbent article. Further, as described in relation to FIGS. 1 and 2, the second end portion 14 of the chassis comprises the fastening device 48, 49 for securing the second end portion 14 of the chassis to the belt portion so that the article assumes a pant-like shape with the belt portions forming a part of a waist portion of the pant. The fastening device 48, 49 typically comprises a set of two fasteners, as shown in FIGS. 1 and 2. However, it may also be provided as an extended piece of a fastener across a length of the second end portion, as seen in the transverse direction Y. The second end portion 14 of the chassis may be secured to any one of the belt portions 16, 17. Typically, the second end portion 14 of the chassis may be secured to both belt portions 16, 17.

Further, as shown in FIGS. 1 and 2, the first and second belt portions 16, 17 are folded over the first surface 21 to form the folded belt configuration prior to use of the article, whereby the first belt portion 16 is arranged on top of the second belt portion 17. In FIGS. 3a-3c , this type of folded belt configuration is illustrated by the belt portions in an exploded view for ease of illustrating the components of the belt portions.

As mentioned above, there is a belt-opening trigger zone 50 disposed on the first belt portion. The belt-opening trigger zone 50 is arranged adjacent the free end 11 of the first belt portion 16. In this manner, a wearer or caregiver is not only guided to identify the free end of the first belt portion when the belt portions are in the folded belt configuration, but also triggered to open up the belt portions, i.e. unfold the first folded belt portion, prior to placing the belt and the article around the waist of the wearer. In other words, the belt-opening zone is adapted to identify the free end of the first belt portion when the belt portions are in the folded belt configuration to trigger a user or wearer to initially unfold the belt portions into an unfolded belt configuration. In this context, the unfolded belt configuration refers to a configuration in which each one of the belt portions are unfolded from the first surface of the chassis. A belt-opening trigger zone arranged adjacent the free end of the first belt portion is also useful to distinguish the free end of the first belt portion from the other end of the first belt portion, which is permanently attached to the chassis.

It should be readily appreciated that the term “adjacent” as used in this context typically means that the belt-opening trigger zone 50 is arranged sufficiently close to the free end so that a user is capable of immediately locate the free end. Thus, the belt-opening trigger zone 50 should at least be arranged at the section of the first belt portion being located closer to the free end 11 than the side edge of the first belt portion being permanently attached to the chassis. The distance between the belt-opening trigger zone 50 and the free end 11 may however vary depending on the dimensions of the belt portion and the chassis, and the general size of the article.

As shown in the example illustrated in the FIGS. 3a-3c , the fastener 51 is arranged on the first belt portion in-between the belt-opening trigger zone 50 and the free end 11. However, the fastener 51 may likewise be arranged at another location on the first belt portion depending on the type of article and the dimensions of the chassis and the belt portions.

Optional, although not strictly required, the location of the fastener 51, and the relative orientation thereof, is such that the corresponding mating fastener on the second belt portion 17 may entirely meet to form an interconnection. Thus, the size and orientation of the fastener on the first belt portion, as seen in the direction x and the direction y, typically corresponds to the size and orientation of the mating fastener on the second belt portion, as seen in the direction x and direction y.

Typically, although not strictly necessary, the belt-opening trigger zone 50 defines a pointer 52 directing a user to the free end 11 of the first belt portion 16 when the belt portions are in the folded belt configuration. However, other types of designs are readily appreciated as long as the belt-opening trigger zone is capable of providing the example advantages mentioned above.

Moreover, in this example embodiment, the belt-opening trigger zone resembles the shape of an arrow directing a user to the free end of the first belt portion when the belt portions are in the folded belt configuration. However, other types of designs are readily appreciated as long as the belt-opening trigger zone is capable of providing the example advantages mentioned above.

In the example embodiments shown in FIGS. 3a-3c , the belt-opening trigger zone is printed on the exterior surface 16 a of the first belt portion 16. However, the belt-opening trigger zone may also be an embossed belt-opening trigger zone. In some design variants, the belt-opening trigger zone is a combination of a printed and an embossed belt-opening trigger zone.

In addition, or alternatively, the belt-opening trigger zone may be a label attached to the exterior surface of the first belt portion.

Typically, although not strictly required, a remaining belt section of the first belt portion 16 has an essentially uniform non-patterned exterior surface 16 a. By way of an example, the remaining belt section of the first belt portion 16 is free from distinguishable indicators.

In some design variants, the belt-opening trigger zone 50 comprises a tactile region having a tactile characteristic different than the other parts of the first belt portion.

In some design variants, the belt-opening trigger zone 50 comprises a visual region having a colour characteristic different than the other parts of the first belt portion.

FIG. 3b depicts another example embodiment, in which the belt-opening trigger zone comprises a plurality of belt-opening trigger zone elements 50 a and 50 b.

Thus, in some design variants, the belt-opening trigger zone comprises a plurality of belt-opening trigger zone elements. As an example, each one of belt-opening trigger zone elements are provided in the form of an arrow defining a pointer directed towards the free end of the first belt portion. Further, each one of belt-opening trigger zone elements may typically be arranged to form a pattern over a surface of the first belt portion. With “a pattern” is meant herein an organised arrangement of at least one belt-opening trigger zone element. Such a pattern may be formed by various types of belt-opening trigger zone elements.

The belt-opening trigger zone may have a length in the transversal direction of the belt of about 5-40 mm, preferably a length in said direction of about 10-35 mm, still preferably a length in said direction of about 20-30 mm.

The belt-opening trigger zone may have a length in the longitudinal direction of the belt of about 10-40 mm, preferably a length in the said direction of about 15-30 mm, still preferably a length in the said direction of about 20-30 mm.

In this context, it is to be noted that the transversal direction of the belt may correspond to the longitudinal direction of the article if the belt is arranged to extend perpendicularly from a line parallel to the longitudinal direction of the article. Analogously, the longitudinal direction of the belt may correspond to the transverse direction of the article if the belt is arranged to extend perpendicularly from a line parallel to the longitudinal direction of the article.

Typically, the belt-opening trigger zone is arranged on the exterior surface 16 a of the first belt portion 16.

FIG. 3c depicts another example embodiment, in which a second belt-opening trigger zone 56 is disposed on the second belt portion 17. The second belt-opening trigger zone 56 is arranged adjacent a free end of the second belt portion. The second belt-opening trigger zone may incorporate any one of the examples, features, functions and/or arrangements as described in relation to the belt-opening trigger zone described in conjunction with FIGS. 3a and 3b above, except that the second belt-opening trigger zone is arranged on the second belt portion instead of the first belt portion.

In some design variants, the whole of a part of the free end 11 adjacent a free end edge 11 a is distinguished from the remaining parts of the article by colour, pattern or the like 55.

Further, in all example embodiments described herein, and in other possible example embodiments, a part of any one of the first and second belt portions extending from the first end portion of the article is typically permanently attached to the first end portion. In other words, an end portion 26 of the first belt portion is here permanently attached to the first end portion 18 of the chassis. Analogously, an end portion 27 of the second belt portion is here permanently attached to the first end portion 18 of the chassis.

As mentioned above, the belted article is typically a disposable absorbent article such as a diaper and an incontinence guard. Further, the belted article 10 in this example comprises the absorption body 40 arranged between the first liquid-permeable covering layer 20 and the second substantially liquid-impermeable covering layer 30.

Other embodiments are possible where the belt-opening trigger zone is provided with randomly selected or varied patterns.

The belt-opening trigger zone is typically centrally arranged in the transversal direction of the belt. However, variants are conceivable wherein any desired asymmetry of the arrangement of the belt-opening trigger zone is possible.

In view of the above disclosure explaining how to provide the belt-opening trigger zone on the belt portion, it will be understood that the article is provided with improved ability in terms of triggering a user of the article to find the free end and unfold the belt portions from their folded configuration.

Although several of examples of the belt-opening trigger zone given in the illustrated examples display a pointer or an arrow, a belt-opening trigger zone may naturally be formed by other intermittent or continuous areas, having a trigger zone shape, e.g. a triangular pointer or the like.

The term “nonwoven” is applied to a wide range of products which in term of their properties are located between the groups of paper and cardboard on the one hand and textiles on the other hand. As regards nonwovens, a large number of extremely varied production processes are used, such as airlaid, wetlaid, spunlaced, spunbond, meltblown techniques etc. The fibres may be in the form of endless fibres or fibres prefabricated with an endless length, as synthetic fibres produced in situ or in the form of staple fibres. Alternatively, they may be made from natural fibres or from blends of synthetic fibres and natural fibres.

By “absorbent article” is meant an article that absorbs or is adapted to absorb bodily fluids, such as urine and/or blood.

The disclosure also covers all conceivable combinations of the described aspects, variants, alternatives and example embodiments of the disclosure.

Furthermore, the disclosure is not limited to the aforesaid aspects or examples, but is naturally applicable to other aspects and example embodiments within the scope of the following claims.
